Evaluating User Engagement and Usability in an IT Sustainability Impact Assessment Tool : A Qualitative Study with IT Procurement Officers

Sammanfattning: As electronic waste and unsustainable Information- and communication product consumption is a growing global problem, more effective tools are required for people and businesses to measure and improve their social and environmental impacts. The Agenda 2030 plan for sustainable development addresses this issue and calls for proper and safer treatment of material extraction, recycling and disposal. TCO Development have created an IT impact assessment tool which addresses this specific problem by giving procurers and purchasers the ability to browse and compare sustainable IT products. To be an effective tool, usability and user engagement attributes have to be considered, as well as the context of the user. The target audience of IT procurement officers are defined and a qualitative study is conducted to evaluate which changes to the design are important to implement to increase the usability and user engagement of the IT sustainability impact assessment tool. The evaluation of the tool shows general positive feedback towards the general layout, design and functionality. Only a few severe errors are discovered which are identified to be in the filtering process. Errors regarding the sensitivity of the slider tool, the excess of options when choosing a TCO certificate version, and confusing terminology while choosing a product type are a few problems which are discovered. A few corrective design alterations were presented based on these discoveries. Moving forward, the iterative design process should continue to address the remaining usability errors. Furthermore, developers and designers should prioritize improving the aspects of data accuracy, transparency as well as system integration to improve corresponding user engagement attributes.
